A phase comparison signal generating means 4 generates a phase comparison signal wherein the information bits in the received signal (a) and service bits other than the information bits are dispersed equally with time. A phase comparing means 6 detects the phase difference between the phase comparison signal (d) and read signal (e) and generates a phase difference signal. The voltage-controlled oscillator 8 is controlled by a closed loop which uses a low-pass filter 7 according to the phase difference signal to obtain a regenerated clock.

Title: Wiper device
Inventor: SAKURAI HIDEAKI
IPC: B60S1/38
Filed: 1995-05-11
Abstract: PURPOSE: To sufficiently reduce a reversing sound of a wiper by reducing a loss of force to be changed to reduce pressure contact force. CONSTITUTION: An auxiliary blade 23 is fixed to a wiper blade 11 to wipe out window glass 30 whose wiper wiping-out directional curvature is changed. In that case, only A is offset from blade rubber 22 and only B is offset from a window glass contact surface of the blade rubber 22 according to a curvature change in the wiper wiping-out directional window glass 30 in a reversing position on the window glass width directional end side of a wiper. Therefore, the auxiliary blade 23 is brought into pressure contact with the window glass 30 in a reversing position of the wiper, and force acting on the wiper blade 11 is dispersed, and pressure contact force of the blade rubber 22 is reduced.  That is, since the pressure contact force of the blade rubber 22 is directly reduced on a window glass surface, a loss of force to be changed to reduce the pressure contact force is reduced, and a reversing sound can be sufficiently prevented.
